A.IntroduceOne of the necessary knowledge of a professional software engineer is to know and understandSDLC (Software Development Life-cycle). System development life cycle models are employedfor the development of various system and inventory management system also follows thesame development life cycle.So, in this report, I will describe different software developmentlifecycles and explain the importance of a feasibility study.B.ContentIDescribe different software development lifecycles1.Software development life cycle (SDLC)To know more about SDLC, be sure to understand the definition of Software DevelopmentLifecycle. SDLC is the process of identifying an information system that how to support all thebusiness needs, system design, development and facilitation to provide users with thenecessary things. The system development lifecycle concept applies to a range of hardware andsoftware configuration, as a system can be composed of hardware only, software only, or acombination of both.SDLC is a term used in systems engineering, information systems and software engineering todescribe a process for planning, creating, testing, and deploying an information system.A software development life cycle is composed of a number of clearly defined and distinct workphases which are used by system engineering. Each phase is itself composed of a series ofsteps, which rely on techniques that produce deliverables.In many ways, building an information system is similar to building a house. There are usuallysix stages in this cycle:6
